I've just got a Sony Google TV box and connected it between my TV and T2. Everything seems OK apart from the sound on the HD channels isn't controlled by the remote (either the Humax or Google TV remote). The sound blasts out, but trying turning it down just does nothing. The volume bar appears on screen and moves down to 0 but the sounds stays the same. Pressing the mute button DOES work interestingly, as does pressing TV on the humax remote and turning the volume down works too. Does anyone know why it's happening and how to fix it?
